[NTG-context] Latest ConTeXt won't "--make"

[Max Chernoff]

Hi all,

I've just updated to the latest ConTeXt, but I'm unable to make the
format:

   $ context --make

   The control sequence at the end of the top line of your error message was never
   \def'ed. You can just continue as I'll forget about whatever was undefined.

Commenting out line 559 of math-ini.mkxl fixes the issue.
